Sababarahahiji tiori dimimitian ku panalungtikan, whereaswheréas others are not. A physical theorythéory is a model of physical events and cannot be proved from basic axioms. A physical theorythéory is different from a mathematical theoremthéorem. Physical theoriesthéories model realityréality and are a statement of what has been observed, and provide predictions of new observations.

Physical theoriesthéories can become accepted if they are able to makemaké correct predictions and avoid incorrect ones. Physical theoriesthéories which are simpler tend to be accepted over theoriesthéories which are complex. Physical theoriesthéories are more likely to be accepted if they connect a wide range of phenomena. The process of testing a physical theorythéory is part of the [[scientific method]].

TheoreticalThéoretical physics is just one important part of [[physics]]; the other part is [[experimental physics]]. The difference between theoreticalthéoretical physics and [[mathematical physics]] is that mathematical physics finds the mathematical rigor required in [[mathematics]] to be more important than the contact with experiments and observations.
